MOP.

Specification of Letters Patent.

Patented Apr. 1?, 1917.

Application filed October 24, 1916. Serial No. 127,348.

To all whom z' may concern:

Be it known that I, FREDERICK W. PEN- DERGAs'r, a citizen of the Uinted States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Mops, of which the following is a specification.

This invention relates to a mop composed of fibrous filaments attached to one end of an elongated handle, the central portions of the filaments being clamped to the end of the handle and the end portions thereof depending to form a circular mop body.

The invention has for its chief object to provide an improved construction of the handle and the means for securing the mop filaments thereto, the construction being of such nature that the component parts may be advantageously assembled by blind people to form a strong durable and satisfactory mop.

The invention is embodied in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specicatiom- Figure 1 represents a side elevation of a mop embodying the invention.

Fig. 2 represents a section on line 2h2 of Fig. l.

Fig. 3 represents a sectional view showing the handle and the filament-securing means as relatively arranged prior to the operation of applying and securing the mop filaments.

Fig. 4 represents a top plan view of the parts represented by Fig. 3, and in addition thereto a plurality of bunches of mop filaments extending in various directions across the end of the handle.

Fig. 5 represents a perspective view of the part hereinafter called the spider.

In the drawings,-12 represents a. handle which is preferably a somewhat elongated wooden rod adapted at one end portion to be grasped by the hand of the user. The op posite end portion of the handle is of circular form and constitutes a clamping end face against which the mop filaments are clamped. I prefer to provide a recess in the clamping end of the handle, thereby forming a concave or cupped clamping face 13 surrounded by an annular ridge 14.

In making up a mop, the handle 12 is mounted vertically on a suitable support with its clamping face 13 upward, as indicated by Fig. 3. A member, such as a wire nail having a single shank 15 and a head 16, is then inserted in an orifice 17 in the center or hub portion 1S of a spider, formed as hereinafter described, and driven partly but not to the full extent into the handle, the nail being driven into the center of the face 13 and into the longitudinal center of the handle and extending lengthwise of the handle.

rIhe operator now places upon the end face of the handle a plurality o f bunches 19 of mop filaments, preferably composed of strands of cotton yarn or thread. The central portions of the bunches are laid upon the end face of the handle, the spider being hold raised by the operator and laterally confined by the nail until the desired number of bunches have been inserted or assembled. As indicated by Fig. 4, the bunches 19 extend in various directions, the central portions of some of the bunches extending across those of other bunches. When enough bunches have been assembled to form a flexible mop body 19aM of suitable size, the securing member 15 is driven farther into the handle, as indicated by Fig. 2, thus causing the spider to compress the central portions of the bunches and press some of the filaments into the concave face 18. rIhe operation of completing the driving of the member 15 therefore causes the brush filaments to be securely clamped in place so that they cannot be displaced endwise.

lThe spider which is formed to bridge the end face of the handle, includes arms radiating from the hub portion 18, as shown by Fig. 5, said arms having inwardly projecting fingers 2O which abut against the margin of the end face and laterally confine the bunches as indicated by Fig. 4.

lIhe concave end face 13 having the marginal ridge 14 coperate, with the spider and its fingers in firmly clamping the central portions of the filaments.

The fingers 20 abutting against the margin of the end face are interposed between the adjacent bunches of filaments and se curely confine said bunches without being visible at the exterior of the mop.

'Ihe fastening member, composed of a single headed shank driven into the longitudinal center of the handle, is free from liability of splitting the handle, and is adapted to be easily driven without liability of deu flection or crippling.

I clai1n:-

A mop comprising a handle having a clamping end face, mop filaments arranged in bunches the central portions of which eX- tend across said face in various directions, a clamping spider formed to bridge said lace and composed of an apertured central hub and arms radiating therefrom and pro- Yvided at their outer ends with inwardly projecting fingers, which abut against the margin of said face, and a securing member composed of a shank passing through the hub aperture, driven into the longitudinal center of the handle, and extending lengthwise thereof, and a head bearing on the Copies of this Ypatent may be obtained for outer side oi' the spider hub, said securingv member being adapted When partially driven, to conne the spider spaced from said end face While the -laments are being assembled, and when completely7 driven to cause said fingers to abut against the margin of said ace.
